单管高压旋喷扩体技术与植筋旋喷桩技术的研究与应用

Application of and Research on Single-tube High Pressure Grouting Technique and Reinforced Chemical Churning Pile Technique

摘要:

单管高压旋喷工艺简单，但成桩直径小。就改进单管法工艺，扩大成桩直径，并在其成桩固结体中植入钢筋笼的工艺技术与作用机理进行了探讨。

Abstract:

The Single-tube High Pressure Grouting Method is quite simple, but the diameter of pile formed by this method is smaller. The improvement of the Single-tube High Pressure Grouting Method, how to amplify the diameter of the chemical churning pile, the craft of plug reinforcement cage in chemical churning pile and the mechanism of this method are deal with in this paper.
